Many building automation systems include smoke detectors and smoke alarm systems. Smoke detectors and alarms based on the MSPM0L134x microcontroller can handle the entire signal chain within a single device. Furthermore, the extreme sensitivity to low currents of the integrated TIA makes the smoke detectors and alarms responsive to small amounts of smoke in the air. Naturally, the low-power leakage of the integrated TIA, the overall low power requirements, and the standby power mode of these microcontrollers allow the smoke detectors and alarms to operate normally under the lowest possible current supply.

Figure 3-1 displays some building automation systems that require the ability to monitor several sensors at once.
